PETER JAMES CAIRNS, OF CHICAGO, ILLINOIS.

PEN HOLDER.

SPECIFICATION forming part of Letters Patent No. 444,046, dated January 6, 1891.

Application filed August 29, 1889. Serial No. 322,361. (No model.)

To all whom it may concern:

3e it known that 1, PETER JAMES CAIRNS, a citizen of theUnited States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pen-Holders; and I do here-v by declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pen-holders; and the invention consists in a holder having a duplicate set of barrels, one within the other, and adapted to hold oneor'more pens, all as shown and described, and particularly pointed out in the claims.

Figure 1 isa longitudinal section of my improved holder. Fig. 2 is a cross-section on line or 0:, Fig. 1. Fig. 3 is a perspective view of the inner barrel or tube, and Fig. 4 is a plan view thereof.

The design of the invention is to furnish a holder which may be converted from a single pen-holder to a double pen-holder, thus affording a feeding or supply arrangement, whereby the device in a sensebecomes a fountain-pen or a pen carrying an extra supply of ink stored for gradual use; or, on the contrary, the double holder or arrangement may be changed to a single holder and the pen be used as ordinarily.

To these ends I employ two barrels, tubes, or cylinders A B. The outer tube or barrel is adapted to the stem 0 in any suitable way, and is straight and plain in the portion extending beyond or below the stem. The inner barrel or tube B has the form of a convolute spring with overlapping free sides of sufficient width in their overlapped portion to receive and hold a pen d between them, while the outer lap or portion forms the inner seat or hearing for a pen a, thatis held between it and the outer barrel. The inner barrel in its original formation has beads b or ribs struck up on the overlapping portion to bear against the inner surface of the outer pen and hold it a sufficient distance from the inner pen to enable the two pens to work together advantageously as contemplated. The convolute form of inner barrel affords a yielding holder for the introduction of both pens o d, so that either pen can be introduced or removed independently of the other, and either can be used separately or with the other, and the holder will be sufficient and convenient in either case.

In order that the beads I) should retain their shape and not flatten out when the sheet is formed into shape for use, I out curved slits e on either side of said beads. This enables me to bend the sheet into cylindrical form without affecting the shape or elevation of the beads. The innerand outer barrels have their extremities on about the same vertical plane, and the two are riveted or otherwise suitably fastened together at their lower portion.

Ordinarily when two pens are used the upper one becomes the feeder, while the lower one is used for writing, and the ink is held in considerable quantity by capillary attraction between the two. A quantity of ink can be thus stored and a considerable amount of continuous writing done without replenishing the ink. The feeder, whether it be part c or 01, need not necessarily be a pen, asa suitable stub of sheet metal or the like instead of the pen would answer the purpose. However, a worn-out pen 0 is preferred, as it costs nothing and always is on hand, and can be exchanged for another worn-out pen when necessary. It is but the work of a moment to change from a single to the double form or back again at pleasure. In other respects my improved holder has the appearance of other common holders, and it is as convenient as any for single use. When the lower pen is used as a feeder, it should be pressed up far enough away from the point of the upper pen not to interfere with writing, which is easily done, as there is abundant room to adjust either pen up and down with respect to the other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A pen-holder having separate barrels, one within the other, and the inner barrel having free overlapping edges or sides, substantially as set forth.

2. A pen-holder formed of barrels, one within the other, the outer barrel being a plain cylinder and the inner barrel a cylinder having free overlapping sides, substantially as set forth.

3. A pen-holder having two barrels, one of which has free overlapping sides with a bead on the overlapping portion and extends within the other barrel, substantially as set forth.

4. A pen-holder provided with separate seats for a pen and feeder,between which is a yielding portion of the holder provided with a bead 01' other means for holding the pen and feeder apart, substantially as set forth.

5. A pen-holder having an inner barrel of convolute form and an outer barrel to which said inner barrel is secured, substantially as described.

In testimony whereof I hereunto set my 20 hand this 10th day of August, 1889.

PETER JAMES CAIRNS.
